Why Replace Your Cabin Air Filter in Spring?
The cabin air filter in your Explorer ST is your first line of defense against airborne contaminants. It traps dust, pollen, mold spores, and other particles before they enter the cabin through the ventilation system. According to the AAA, a cabin air filter can capture everything from dirt and insects to allergens like pollen, which is especially important during spring when pollen counts soar.
For the 40 million Americans suffering from allergies, a clean filter can reduce symptoms like sneezing, itchy eyes, and runny noses, which could otherwise distract you while driving.
Springtime also brings early blooming due to warmer temperatures, with some regions seeing flowers and trees bloom up to three weeks earlier than usual. This extended pollen season means your cabin air filter works harder and clogs faster. A clogged filter not only reduces air quality but can also strain your HVAC system, leading to reduced airflow and potential damage. Regularly replacing it—especially in spring—ensures you breathe cleaner air and maintain optimal vehicle performance.
How Easy Is It to Replace?
Good news: replacing the cabin air filter in your Ford Explorer ST is a quick and straightforward task that most owners can tackle in under 10 minutes—no advanced mechanical skills required! The process involves accessing the filter behind the glove box, swapping out the old one, and installing a new one.
Step-by-Step Guide to Replacing Your Cabin Air Filter
Supplies: You’ll need a replacement cabin air filter compatible with your 2023 Ford Explorer ST. I recommend the EPAuto Cabin Air Filter for its activated carbon layer that enhances air quality and traps allergens, and MERV 13 rated! You will also need a phillips head screwdriver.
Locate the Filter: The cabin air filter is behind the glove box. Open the glove box and release the side clips or stops (consult your owner’s manual for specifics). Lower the glove box to access the filter compartment.
Remove the Old Filter: Open the filter compartment cover, pry open the the plastic tabs on the sides. Then slide out the old filter, noting the airflow direction arrow. Check the filter—it’s likely packed with dust and debris after a season (or two) of use.
Install the New Filter: Insert the new filter, ensuring the airflow arrow matches the direction of the old one. Secure the compartment cover.
Reassemble: Reattach the glove box by reversing the removal steps. Make sure it closes properly.
Test Your System: Turn on your vehicle’s ventilation system to confirm airflow is strong and clean.
